Sixty-lawyer ‘new law’ corporate firm Cubism Law has been hit with dozens of departures, leaving its future in doubt.

Founded by former Fieldfisher partner Andrew Pena, the Holborn-based firm stands to lose about 16 lawyers to ‘challenger’ corporate boutique Gunnercooke, according to people with knowledge of the move. Six have already been confirmed, one person added. The boutique is also hiring many of Cubism’s support staff.
